Effects of HCMVsn and IFN-α2 on ADCC of NK cells from HIV-infected individuals. (A) ADCC within the HIV-infected group was measured in 51Cr release assays over 5 h at E:T 30:1 in the presence of a 1:5 dilution of HCMVsn or 20 pg/mL recombinant human IFN-α2 as previously described and compared to untreated conditions (n = 21). (B) Baseline ADCC levels were compared between the three groups of HIV-infected individuals distinguished by HCMV serostatus and fraction of NK cells expressing NKG2C. Error bars represent median with IQR, performed in duplicate with conditions compared using Wilcoxon signed-rank test.
